Sniffer dogs went to work in the rubble to find those who are still trapped, Amalia Tedeschi, an official with Italian firefighters, told RAI state TV. She said that injured people had been extracted alive. Rescue and recover crews continued to work overnight Tuesday into Wednesday morning.

The Associated Press reports that a section of the Morandi Bridge collapsed over an industrial area during the storm, which began suddenly. That section of the Morandi Bridge is about 180 feet high. The part that collapsed is about 260 feet long, while the full bridge is about .6 miles.

The head of Italy's civil protection agency, Angelo Borrelli, said 30-35 cars and three heavy trucks were on the part that collapsed.
